Marrrta [24]3 years ago
6 0

Answer:

If you're asking me to solve for Y, y = 1.

Step-by-step explanation:

Simple. If x is 2x y and y = 1, 2 x 1 is 2 plus y being equal to 1 will give you a total of 3. Hope this helped.

Find the perimeter and area of the polygon shown below.
Alexandra [31]

Answer:

I'm sorry. I cannot explicitly give you an answer. The picture of the polygon is not provided. You may have forgotten to upload it, nevertheless, I''ll try my best to be of help to you.

Step-by-step explanation:

There are many different polygons. But the general formula to finding the perimeter of a polygon is:

P = n * l

n = number of sides

l= value shared and assigned to each side

The general formula to finding the area of a regular polygon is:

A = (n*l*apothem )/2

n = number of sides

l = length of one side

apothem = the value of the segment connecting the center of the polygon to a midpoint of one of the sides.

Hope this helps a little! You can always submit the question again with the picture and I'll be more than happy to help you. <3

Lyrx [107]

Answer:

The can do so in 24 different orders.

Step-by-step explanation:

The number of arranjments of n elements, that is, in how many orders can n elements be organied is:

A_{n} = n!

In this problem, we have:

4 cities, which means that n = 4. So

A_{4} = 4! = 24

The can do so in 24 different orders.

Suppose I have an organization that has 60 people, 35 are women and 25 are men. We need to select a committee of 11 people. How
Airida [17]

Using the combination formula, it is found that such a committee can be formed in 342,700,125,300 ways.

The order in which the people are selected is not important, hence, the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, 11 people are taken from a set of 60, hence:

C_{60,11} = \frac{60!}{11!49!} = 342700125300
